FLOAT-VALVE.

Specification of Letters Patent. Patented J 3, 18, 191() Application filed duly .26, 1909. Serial No. 509,473.

To all whom it may concern:

Be it known that 1, CHARLES J. KIRK, a citizen of the United States, residing at N ew Castle, in the county of Lawrence and State of Pennsylvania, have invented new and useful Improvements in Float-Valves, of which the following is a specification.

This invention relates to improvements in float valves and more particularly to a ballcock for flushing tanks.

It is the object of this invention to provide a valve of this character operated by a float resting on the surface of the water in the tank through the means of a compound lever, and to provide in combination therewith a valve seat and valve washer so arranged that the same may be removed and replaced without detaching or otherwise at.- ."tecting the arrangement of the operating mechanism. By this construction the washer carried in the plunger head of the valve, is always accessible for removal and replacing when the same becomes worn, and the valve seat may either be replaced or refaced at the same time. disconnect any part of the operating mechanism of the valve forthis purpose the advantages of the same are obvious. V

\Vhile the preferred form of this invention is illustrated in the accompanying sheet of drawing, yet it is to be understood that m nor deta l changes may be .made

without departing from the scope thereof.

Figure 1 is a viewin side, elevation of the complete valve constructed in accordance with this invention. Fig. 2 is a central loIlgitudinal sectional view showing the valve in closed position. Fig. 3 is a central longitudinal sectional view showing the valve in open position.

l The main body or casing 1 of the valve to which the operating parts are secured is arranged entirely within the walls of the tank and is secured thereto by the integral extension 2 adapted to pass through one wall 3 and be secured thereto by a locking nut 4: on the exterior thereof, and form at the same time a connection with the supply pipe. The casing or valve body is cylindrical in shape forming an open ended valve chamber 5. on each side of the casing extending: from the open end a short distance inward.- A

discharge tube 7 is provided near the base of the valve chamber to which a pipe may be attached if desired to discharge the water Since it is not necessary to A horizontal slot 6 is provided at the bottom of the tank. The orificei i on I the side of the discharge tube 7 nearest the wall of the tank is for the purpose, when a pipe leads'from tube 7, of diverting a portion of the discharge against the Wall of the tank to prevent splashing as the tank fills.

v Integral ears 8 and 9 are provided upon the upper and lowersides of thecasing for the attachment of the operating levers.

The valve seat 10 is formed at the free end of the detachable tube 11 centrally secured to the casing at the bottom of the valve chamber and extending beyond the'open end of the chamber 5. The valve plunger 12 is in the form of a sleeve, the outer sides of which engage the inner walls of the valve chamber and whose inner diameter is considerably larger than that of the tubular sea member 11. Pins or trunnions 13 are provided on opposite sides of the plunger adapted to engage and extend beyond the longitudinal slots 6 in the walls of the casing. The exterior end of the plunger is closed by a detachable screw threaded cap 14 containing a removable washer 15 which is securedbetween the-base of the cap and the walls of the-plunger. t

The operating mechanism comprises a ball arm 16 pivoted to the ear 8 on the upper side of the casing having a right-angle extension at the pivotal point. The customary float is attached to the free end of this arm,

- and since this part of the mechanism is old and well known the float has not been illustrated 111 .th1s instance: Plvotally secured at their lower ends to the ears 9 depending from the casing are two arms 17 of a wishbone bracket, which extend: upward on each side of'the cas ng and are o1ned together above the ball lever 16. A pivoted connecting link 18 joins the upper end of this bracket to "the, rectangular projection from the ball lever. The pins or trunnions 13 extending through the slots 6 in the side' of the casing 5 from the plunger 12 are pivotally secured in the opposite arms 17 of the wishbone bracket,

The operation of this valve is as follows,

As seen in Fig. 2 the valveis closed when the tank is full. As the ball floats on the surface of the water the free end of the ball When the tank is emptied the free arm of the ball lever descends with the surface of the water thereby forcing the wishbone bracket outward which in turn will move the valve plunger outward removing the washer in the detachable cap from contact with the valve seat and allowing the water from the supply pipe to pass through the integral extension, the tubular seat member, around the space between the tubular seat member and inner walls of the plunger to the discharge orifice. As the surface of the water in the tank rises the operation will be reversed and again close the valve seat by the washer in the detachable cap being brought in contact therewith.

It is seen by this construction that whenever it is necessary to have access to the inner parts of the valve operating mechanism it is only necessary to remove the cap upon the exterior of the valve plunger, which will allow the replacing of a worn washer, and the removal, refacing and replacing of the tubular valve seat. This construction is especially advantageous in connection with the compound lever operating mechanism, since it is not necessary to disconnect or remove any of the parts of this mechanism to have access to the interior of the valve casing or the working parts therof.

What I claim is 1. In a ball-cock, a casing having a discharge orifice, a removable valve seat extending without said casing, I a plunger sleeve surrounding said valve seat, a removable plunger head closing the exterior end of the plunger sleeve and means to reciprocate said plunger sleeve.

2. In a ball-cock, a casing, a valve chamber provided with a discharge orifice, a valve seat within said chamber, a plunger sleeve surrounding said seat and adapted to reciprocate within said chamber, a detachable plunger head, a compound float operated lever pivoted to the casing adapted to reciprocate the plunger sleeve.

3. In a ball-cock, a casing, a valve chamher having a discharge orifice and parallel slots in the sides thereof, a valve seat, a valve plunger having pins extending through said slots, a detachable plunger head, a pivoted ball lever and a connection between said ball lever and said pins to reciprocate said plunger.

4. In a ball-cock, a casing open at one end forming a valve chamber provided with a discharge orifice near the closed end thereof, a hollow plunger sleeve adapted to reciprocate in said chamber, a detachable tubular member extending from the source of supply forming a valve seat within said plunger sleeve, a detachable plunger head on the extremity of said plunger sleeve and means to reciprocate said plunger sleeve.

5. In a ball-cock, a casing open at one end forming a valve chamber, a tubular seat member leading from the source of supply and extending beyond the casing, a reciprocating plunger sleeve engaging the walls of the chamber adapted to uncover the valve seat, a detachable plunger head on the exterior of the plunger sleeve, a discharge orifice provided in the casing leading from the chamber and means independent of the seat member and plunger head for operating the plunger sleeve.

6. In a ball-cock, a casing forming an open ended valve chamber provided with a discharge orifice near the closed end thereof and parallel slots in the side walls thereof, a tubular seat member extending therebeyond provided with a valve seat at the extremity thereof, a reciprocating plunger sleeve having pins projecting from the sides adapted to engage in said slots, a removable screw cap on the exterior of the plunger sleeve, a removable washer therein adapted to engage the valve seat, a wishbone bracket having its arms pivoted to the casing, a bell crank ball lever pivoted to the casing and a pivoted link connecting one arm of said lever to the joined arms of said bracket.

7. In a ball-cock, an open ended valve chamber, a tubular seat member leading from the source of supply centrally arranged therein and extending thercbeyond, a valve seat at the extremity thereof, a hollow valve plunger engaging the walls of the chamber and forming a passage way between the inner walls thereof and the tubular seat member, a removable screw cap on the extremity of said plunger, a removable washer secured between the cap and walls of the valve plun er, means for reciprocating the valve p unger and a discharge orifice provided in the valve chamber at the rear of the valve plunger.
